Volkswagen Jetta 2015: MOT failure rate for its age
23.9% of 7,574 MOT tests of the Volkswagen Jetta first registered in 2015 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 95.4 (95% CI 91.0–99.7; 100 = normal for this model at that age): close to other build years of the same model at the same age (within 5 points of normal).
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 23.9 | % | all ages tested | 2019–2024 | 7574 |
| Index against this model at the same age (95% CI 91.0–99.7) | 95.4 | index | 100 = normal for this model at that age | 2019–2024 | 7574 |
| Rank among this model's 13 build years | 3 | of 13 | 1 = fails least for its age | 2019–2024 | 7574 |

How every figure is calculated: methodology. Age, test year and build year are tied together (age = test year − build year), so the test-year level is taken as observed, not estimated.
